To ZZ 107mm it may concern v Be it known that I, NIooLAY NELSON, .a citizen of the United States, residing at Waukegan, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in Garment-Pressing Machines, of which the following is a specification. j y

This invention relates to garment pressing machines in which great pressure is desired to be exerted at times on the garment or article to be pressed, lalthough the degree of pressure may be-varied tosuit different conditions.

The objects of this invention are to provide a machine of this character in which the power may be furnished either by the operator or from some suitable source of power, but preferably the latter; vto'provnle a power-driven machine' 1n which. the presscr-iron may be caused to` be qulckly moved into pressing position by a slrnple action of the operator, and the presser-iron then held in pressingposition for. a predetermined time and then returned to normal inactive position without further action on the part of the operator, or the iron may be held in pressing position as long as de-l sired by the operator.` t

Further objects of my inventlon are to provide a machine of this character, whichl is strong and substantial in construction and which will requirecon'iparatively little attention or adjustment in operation.

I accomplish these objects, and such other advantages as will appear hereinafter, by means of the machine shown in' the accompanying drawings, in which :v

Figure l is a side view of lthe same, parts being broken away or omitted for convenience in illustration, l? ig. 2 is a sectional detail plan View showing the connections between the toggle link and presser arm lever, Fig. 3 is a rear elevation on an enlarged scale, partsl also being broken away or omitted, Fig. 4 is a detail view showing the arrangement of a trip'rod lfor a catch, Fig. 5 is a detail side view showing the principal automatic controlling .or operating devices in normal or inactive position, and Fig. 6 is Aa similar view showing the parts in position when the. machine is thrown into pressing action by the operator.

As shown in these drawings, 8 indicates a strong substantial frame upon which is mounted a presser table 9; The frame is ing the presser iron 16. The lever 11 is provided at its lower end with a cylinder 17, which is preferably madeintegral therewith, this cylinder being open at its front end and closed at the back end, as clearly shown in Fig. 2. A heavy compression spring 18 tits within the cylinder 17 and is engaged at the open end of the cylinder by a plunger 19, which engages with a yoke 20. A bolt 21 passes through the cylinder, plunger and yoke and is provided with a nut 22, whereby the tension of the spring may be adjusted.

In order that the machine may be operated by the action of the operator, I provide an extension 23 on the lower side of the cylinder 17|, which is provided with a pin 24 fitting in a slot 25, in a link 26 which is con nected with a bent foot lever 27. This foot lever is pivoted to a rod 28 in the frame of the machine, and has a pedal 29. It will be readily seen that when the operator presses down on the pedal the lower end of the lever-,11 will be pressed backwardly or to the left as shown in Fig. 1 and will cause the presser iron 16, to engage with the garment or article placed on the table 9. A spring 30 is provided for holding the lever 27 in normal position and the slot 25 permits the lever 11 to be operated without moving the foot lever 27 when the machine is driven by power.

The power driven connections for the machine are as follows: The yoke or crosspiece -20 is provided with trunnions 31, which are connected by meansof connecting rods 32 with hollow trunnions 33, at the upper end otv a toggle block or link A bolt 35 .passes through the hollow trunnions 33 4and serves to hold the ends of the rods 32 in position. The block 34 is cut away for a short distance at the center thereof, which exposes the central portion of the bolt.l

` gaged at times by a crank arm 37, which arm hangs vfrom a crank 38 1n a crank shaft 39, L `wh1ch shaft 1s supported 1n bearings 4() at the rear .part of the machine. This shaft is driven by means of a gear 41,` which meshes with a pinion 42 on a driving shaft 43, which shaft is supported in bearings 44 on the rear part of the frame. The shaft 43 may be driven in any desired manner, for instance by means of a pulley 45, this pulley being preferably made suiicientlyl heavy so that it will also serve as a ily wheel.Y

It will be readily seen that whenlthe end of the crank arm 37 engages with the free end of the. toggle arm 34, the central portion of the bolt 35 being exposed to forma convenient bearing, it will press the toggleiron may be held in depressed position for' a predetermined time, or at the will of the operator. These hooks or catches are securely fastened to a bar 50, pivoted at 51 to the frame of the machine and extending inwardly .a sufficient distance, or suiii'ciently weighted, so that the inner portion of the bar will out-weigh the outer portion and connected parts and tends to throw the hooks or catches into engaging position. The catch strip or member 49, is extended upwardly 'a short distance and is provided at the top with a pivoted block 52, having a rod 53 extending therefrom, as best shown in Figs. 5 and 6. This rod passes freely through a pin 54 extending out'from the face of a weight or pendulum 55. This pendulum is pivoted at 56 to an arm br projection 57 from the bracket 36. A compression spring 58 fits lover the rod 53 between the block 52 and pin 54. The weight or pendulum 55 is, at times, swung from side to side to accomplish certain controlling operations, and the spring 58 is only sufliciently long so that when the weight is swung to` the left as indicated in Fig. 5, the catches 48 and 49 will be swung out of the engaging position. The weight or pendulum 55 is provided with a rod or pin 59 which engages with the crank arm 37 and, when the crank is turning, holds this arnrout of engagement with the toggle bolt 35 until the operator desires to start the presser'in action. This is accomplished by swinging the weight 55 over to the right as indicated in Fig. 6 which swings the in 59 over asuiiicient distance to permit t e'lower end of the crank arm 37 to engage with the bolt 35. This weight is swung by means of a rod 60 which extends down' throughthe frameand has its lower end resting on the end of a foot lever`61, this lever being pivoted at 62 to a support 63 from any convenient part ,of the frame, preferably from the rod or shaft,28. The upper end of the rod 60 may engage directly with. the lower outer corner of the weight 55, but I prefer to have it engage with the lower bent end 64 ofsabar 65 which is pivoted at 66 to the 'weight 55, and which extends upwardly through a hearing 66 and is provided adjacent to its upper4 end with a notch 67.l This bar serves at times for holding the weight 55 in the position indirod 70, supported in'bearings 71, this construction being clearly shown in Figs. 3 and 4. The rod 70 is also provided with an'arm 71 which extends forwardly and is pivotally connected to a bent ro'd 72 which rod passes down and over the upper end of one of the projections 47 on the toggle 34 and engages with a bearing 73 on the frame. This arrangement is Asuch that when the toggle 34 is up, the rod 72 will be raised, thereby raising the arm 71. and swinging the rod or shaft 70 so that the pawl 68 will be in engaging position. When the toggle 34 is pressed down, the weight of the arm 71 and y rod 72 will turn the shaft 470 and swing the pawl-68 up out of engaging position.

In order to swing the weight or pendulum 55 back to normal or inoperative position, I provide it with a tappet-74 which is pivoted thereto at 75 and rests against a stop 76 on the face of the weight.. A spring 77 tends to hold the upper end of the tappet 4 against such stop, the spring being suiiciently strong so that when the upper end of the tappet is pressed to the left as shown in Fig. 6 it will swing the weight or pendulum 55 tc the left. This tappet is adapted to be engaged by a cani or projection 78 on the crank shaft 39.v The Weight 55 is preferably prevented from swinging too far to the right by means of a stop 79, asshown in Fig. 6. Y l

The machine may be driven by means of a beltfnot shown) or in any other desired manner. Assuming that the drvingshaft- 43 is being driven at the proper speed, the operation of the machine is as follows: The operator places the garment or article to be pressed on the table 9 and then adjusts the presser iron 16, this adjustment being ordinarilysulicient to regulate' the pressure desired. He then presses down on the outer end of the lever 61, which raises the rod 60 and. throws the pendulum 55 over to the Lomas right as indicated in Fig. 6. This also raises the bar 65 so that the notch 67 will be engaged by the pawl or catch 68, and' will be held in raised position. It will be noted that, at such time, the toggle arm 84 is in its normal raised position as indicated in full lines in Fig. 4, which holds the catch 68 in proper position to engage with the notch 67. |Ihe movement of the weight or pendulum 55 causes the pin 59 to Swing over a sufficient distanceto allow the crank arm 37 to engage with the bolt 35 Iin the toggle arm 34, and as the crank arm moves down the toggle will be forced downwardly, which causesthe connecting rods 32 to draw the'lower end of the presser arm lever 11 back. This brings the presser-iron 16 into pressing engagement with the article on the table 9. Ordinarily, it is desirable to maintain the pressure for a greater length of time than would be ob tained by a single downward movement of the crank arm 37, but it is also desirable to relieve the pressure after a short predetermined time. For this purpose the projections 47 on the toggle arms 34 are engaged by the catches 48 .and 49, and the toggle is thereby held in depressed position, thus maintaining the pressure on the garment. It will he noted that when the .toggle arm 34 is in' such depressed position, the rod 72 is free to move downwardly so as to throw the catch 68 out of engaging position, and thereby release the bar 65. Then, as the crank shaft 3) continues its revolution the cam 78 will strike the tappet 74 and throw the weight or pendulum to the left as indicated in Fig. o. The pressure on the springv 58 is then suiicient so that the catches 48 and 49 will be thrown out of engaging position as soon vas the toggle arm 34 is slightly depressed so as to relieve them. The crank arm 37 then moves down and engages aga-in with the bolt and presses the toggle down sufficiently to release these catches, then, as the crank arm moves upwardly,the toggle arm 34 follows itin its upward movement,

until such if toggle arm reaches its normal position, this .upward movement of the togglo arm being caused by the springs 18 and 46. The weight 55 is now in such position that as the crank arm 37 again swings over and starts on its downward movement, it will be engaged by the pin 5) and deflected from the bolt 85 and may continue such movement withoutaictuating the machine until the operator again presses on the foot lever 61, when such operation will vbe repeated. The return of the toggle 34 to raised position again raises the, rod 72 and throws the catch 68'int'o engaging position.

The principal object of this catch is to insure the holding of the weight 55 in proper position to cause the machine to operate when the operator presses on the foot lever (3l. It the weight were swung. atl such -time that the camvwould immediately engage withthe t-appet 74, the weight would be thrown back and the crank arm prevented from actuating the toggle. The bar and catch 68 insure the holding of this weight in proper position until the crank arm has actuated the toggle, when the weight is then free to be thrown over by the cam on the next revolution of the crank shaft 39. It will be noted that by means of this arrangement, the presser arm is swung down on the downward movement of the crank arm and isheld in vdepressed position during one revolution, and is then released upon the next downward movement of the crank arm. `If the operator desires to keep the pressure on for a longer time, he merely keeps llisfoot on the foot lever 61 which thereby holds the weight 55 in the position shown in Fig. 6, and the cam will throw the 'tappet 74 over without swinging the weight. Therefore, the catches 48 and 4f)4 will remain in engaging position as long as the operator desires and will thereby continue the pressure until he again releases the foot lever. Y i

It will be readily understood by those familiar with the art that my improved machine provides a simple and eflicient mechanism for performing the various operations desired in pressing. It will also be noted that various changes may be made in the details of construction without departing from the spirit of this invention and, therefore,..
